Can I hide certain project categories from overviews or searches?

What I want to do:
I want to be able to look at on the agenda (and eventually, create a new overview search) that only shows me the “not done” notes for all the projects in a top-level project category, rather than all “not done" notes across all projects and categories.

What happened:
I tried to do a search using the name of my project category as the search term.

What I expected:
I expected to see all notes from any project within the project category, but that didn’t work; I only saw those notes that had the actual search string in the note.

Things that might be helpful to know (Agenda version, OS and model, etc):
Agenda 16.1 running on Ventura 13.1 (but just updated, so maybe this is fixed)

This is indeed a popular request that we hope to address in a future update, thanks for the feedback!
